Mattapoisett Lions Triathlon
About this race
Same beautiful venue featuring improved organization with help from local triathletes. Great for beginners and experienced athletes!
Note: Given that we've been getting more non-licensed racers over the past couple of years, we have dropped USAT sanction to save non-licensed racers from having to pay the $15 one-day license.
Group discount for triathlon teams of 10 or more racers! Contact race director..
All proceeds still to benefit Mattapoisett Lions Club charities. Take advantage of early registration and beat the July 1 $5 fee increase!
